other of which the refractive index is different,
then which of the following will change
A
Frequency wavelength and relocity
B
Frequency and wavelength
C
Frequency and velocity
D
Wavelength and velochy​

Answer 1

frequency remains the same

wavelength and velocity changes

n1/n2=V2/V1=w2/w1

I hope this helps ( ╹▽╹ )

Answer 2
